TOWSON, Md. (WJZ)— The Towson doctor who was hit by a car while jogging to work Thursday morning is now listed in serious condition.

Dr. Theodore Houk made it his routine to jog to work every day. But Thursday, Baltimore County police say he never made it past Charles Street at Chestnut Avenue. Police say he jogged into a traffic lane and was hit by a 65-year-old driver signaling a turn onto Chestnut.

Thursday afternoon, the 50-year-old doctor was listed in critical condition at Shock Trauma. Monday morning, his condition was upgraded to serious.

The GBMC physician is well known by Towson commuters for his daily jogs along Charles Street to work with a briefcase in hand.

“I don’t know if this day was any different day than any other day. I would assume he was in his usual attire and carrying his equipment and his lunch with him as he usually did,” said Dr. Neal Friedlander, GBMC chairman of the Department of Medicine.

Houk has been on GBMC’s medical staff since 1992 but maintains a private internal medicine practice in the 7400-block of York Road.

Police say the driver who hit the physician remained at the scene. No charges have been filed at this time.
